Description

FIELD OF THE INVENTION [0001]The present invention relates generally to a portable data storage cartridge comprising a first information storage medium and a second information storage medium.BACKGROUND OF THE INVENTION [0002]The need to store and retrieve large volumes of digital data has resulted in the need for data storage devices having ever increasing amounts of storage capacity. Data can be stored, of course, in cassettes, floppy disks, diskettes, hard disks, optical disks, and the like. However, the greater the amount of memory available, the more difficult it becomes to accurately obtain specified data with rapid access times and with maximum system fault tolerance.[0003]Automated data storage and retrieval systems, more commonly known as libraries, jukeboxes or auto changers (collectively referred to herein as “libraries”), are frequently used when there is a need to keep relatively large amounts of data available at a cost per gigabyte which is lower than that of solid st...
